An airship system having a flexible envelope and at least one bladder positioned therein is described. The bladder(s) provide an impervious barrier between the gas within the bladder(s) and the air exterior to the bladder(s). The envelope includes longitudinal and hoops straps weaved together in a criss-cross manner. The envelope also includes rings positioned thereon that include truss members for receiving struts for removably coupling the airship to another airship. A tri-hull delta dirigible system is also described, comprising three airships coupled together using struts and arranged in an equilateral triangle formation. The tri-hull delta dirigible system has a similar lift capacity (volume) as a conventional large mono-hull dirigible, while minimizing the detrimental bending in the center of the conventional mono-hull dirigible.

The dirigible of claim 2, wherein said first and second rings include two linear truss members for receiving removable struts therein. 5. The dirigible of claim 4, wherein each of the airships are removable from the dirigible upon disconnection of the struts from the linear truss members. 6. The dirigible of claim 1, wherein the at least one bladder is sized ten percent larger than the outer envelope. 7. The dirigible of claim 1, wherein each of the outer envelopes of the first airship, the second airship, and the third airship comprises a plurality of longitudinal straps and a plurality of hoop straps coupled together in a criss-cross manner. 8. The dirigible of claim 7, wherein the plurality of longitudinal straps and the plurality of hoop straps form a load bearing component of each of the airships. 9. The dirigible of claim 1, wherein the at least one bladder comprises a plurality of separate sections. 10. The dirigible of claim 1, wherein the at least one bladder forms an impervious air barrier between a fluid filled within the at least one bladder and the atmosphere surrounding the at least one air bladder. 11. The dirigible of claim 1, wherein the fluid comprises helium gas. 12. A tri-hull dirigible comprising, a first truss member;a second truss member;a third truss member; wherein said first second and third truss members are configured in a triangular shape, and wherein said first truss member is generally horizontal;a first airship;a second airship; anda third airship, wherein each of said airships includes a structural ring and an exterior skin that encloses a cavity therein, and wherein said first truss member passes through the cavities of said first and second airship and engages both of said structural rings of said first and second airships in two places, said second truss member passes through the cavities of said first and third airship and engages said structural ring of said first and third airship, and said third truss member passes through the cavities of said second and third airship and engages said structural ring of said second and third airship. 13. The tri-hull dirigible of claim 12, wherein said first, second, and third truss members are removable. 14. The tri-hull dirigible of claim 13, wherein said first, second, and third truss members have an aspect ratio of about 213. 15. The tri-hull dirigible of claim 13, wherein said first second and third truss members are circular with diameters of about eight inches. 16. The tri-hull dirigible of claim 13, wherein said second and third truss members are configured to have a higher resistance to buckling than said first truss member. 17. The tri-hull dirigible of claim 16, wherein said first, second, and third truss members are circular and wherein the ratio of the radius to wall thickness for said second and third truss members is higher than the ratio of the radius to wall thickness for said first truss member. 18. The tri-hull dirigible of claim 13, wherein said truss member are removable and said airships are configurable to be operated independently of each other. 19. The tri-hull dirigible of claim 13, wherein said first, second, and third truss members are joined together by V-shaped truss members. 20. The tri-hull dirigible of claim 12, wherein said structural ring includes a reinforced hole therethrough and wherein said truss members engage said structural ring through said reinforced hole.
